IMPROVEMENT IN EXTI'NGUISHERS FOR LAMPS.

Specification forming part of Letters Patent No. 59,607, dated November 13, 1866.

To all whom it may concern.-

Be it known that I, JOHN N. HOWE, of Franklin, in the county of Merrimack and State of New Hampshire, have invented certain Improvements in Extinguishers for Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which- Figure l is a perspective view of a lampburner with my improved extinguisher applied thereto. Fig. 2 is a vertical section through the center of the same with the chimney and its cap in place.

My invention has for its object to provide a simple, convenient, and efficient means of extinguishing the light of lamps of Various construction, whereby the necessity of removing the chimney and the danger of explosion heretofore occasioned (by blowing the flame in contact with and igniting the gases within the lamp) are avoided; and my inventioncoir sists in an open tube passing from the outside ofthe burner to the top or near the top of the wick-tube, a current of air heilig blown upward through the extinguishing-tube, which is so formed and placed as to direct and concentrate the air at the base of the Haine when it is required to be extinguished.

VTo enable others skilled in the art to understand and use my invention, I will proceed to describe the manner in which I have carried it out.

In the said drawings, A represents the perforated easing of an ordinary kerosene-lamp burner. B is the cap which supports the chimney C, and D is the Wick-tube.

Between the outside of the lower portion of the perforated easing and the upper edge of one side of the wick-tube (and inclined upward thereto) is placed a tube, E, the lower end, a, of which is of a circular form, while toward its upper end it becomes flattened and terminates in a narrow slit, b, exten ding across the whole length of the wick, as seen in section, Fig. 2.

Vhen it is required to extinguish the llame of a lamp it is simply necessary to place the mouth near the orifice a and blow into the tube E, which is of such a forni and so iuclined to the wick that the current of air is concentrated at the slit b, and is so forcibly expelled therefrom as to instantly cut off or extinguish the iiame with but little or no smoke, and thereby prevent any disagreeable odor arising therefrom.

The form and position of the tube E maybe varied somewhat without departing from the spirit of my invention, and the said tube may project outside of the perforated casin g or be provided with a mouth-piece, if desired; but the construction herein shown and described is what I prefer.

Vhat- I claim as my invention, and desire to secure by Letters Patent, as an improve ment in extinguishers for lamps, is

The tube E, through which a current of air may be directed to the iiame, substantially as set forth.

JOHN N. HO\VE.
